DRILL ATTACHMENT FOR PLANTERS.

SPECIFICATION formingpart of Letters Patent No. 513,664, dated anuary 30, 1894. Application filed January 25,1893. derial No. 459,675. (No model.)

To aZZ whom it may concern.-

Be it known that we, ALTON L. BAUGHMAN and DELMER L. BAUGHMAN, citizens of the United States, residing at- Albion, in the county of Noble and State of Indiana, have invented a new and useful Drill Attachment to so construct the drill-shoe as to increase its durability, whereby those parts subjected to the most wear, may when worn, be replaced at a small cost, thus obviating the necessity of removing the entire drill-shoe and replacing it by a new one.

With these objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

In the drawingsz-Figure 1 is a side elevation of a drill-shoe embodying our invention? Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a perspective view of the seed-tube. Fig. 4 is a similar view of the stationary brace portion of the drill-shoe. Fig. 5 is a detail in perspective of the runner or wearing portion of the drill-shoe. Fig. 6 is a similar view of a modified construction of runner, the same being designed to plant corn and form furrows wider than those usually employed in planting.

Like numerals of reference indicate like parts in all the figures of the drawings.

The seed-tube lis provided with the usual seed-passage 2, which extends from its upper end throughout its length and is at the bottom nearly rectangular in cross-section as shown. At its front lower end the seed tube is fiat and extends forward to form a foot 8, and upon the under side of the same and in advance of the opening 2, the aforesaid foot is provided with a tenon 4, which tenon is preferably set within the side-edges of the foot thus forming at opposite sides thereof shoulders 5. The foot, furthermore,in cross section is preferably tapered slightly, or in other words,its opposite faces converge toward the lower and front edges thereof. The blade extends from the front or toe of the foot 3 to a point adjacent or a slight distance in advance of the seed-passage 2, where it terminates and has its lower corner or portion provided with a curved recess 6. its ends the blade is also provided with one or more bolt or rivet holes 7.

8 designates a pair of converging draftstraps or braces which are provided at their upper ends with holes 9 by which they are connected through the medium of bolts or otherwise to the framework of the seeder. The lower ends of the straps 8 are securely bolted or riveted at opposite sides, as indicated at 10, to a pair of steel-plates 11, which from their point of juncture gradually diverge toward their rear ends and slightly converge toward their lower edges in the same ratio as do the sides of the tenon 4E formed'on the under side of the foot 3 of the seed-tube.

12 designates the runner portion of the device, and the same is provided with a lower curved edge 13, produced by reason of the said section 12 being of a substantially V- shape when viewed in cross-section; The curved edge has its lowest point at the rear end of the runner-section, and above said point there is formed in said runner-section, the seed-discharge opening 14, which is continued upwardly through a lug or tenon 15, formed on the upper side and at the rear end of said runner-section. This lug or tenon 15, is formed within the opposite edges of the runner section, and is provided at its front edge or side at the juncture with the runnersection with a curved lug or extension 16, having a hole 17. The upper end of the lug 15 is flat, and is designed to [it the under side or heel of the seed-tube 1, so that the seed passages of the tube and runner-section form a continuous passage with each other. The seed-passage or opening 14 that is formed Between.

within the runner-section is curved rear- ICC top of the soil, but instead will fall into the botom of the furrow. The rear end of the runner-section is beveled orinclined as indicated at 19 which prevents the seed chamber from becoming choked or clogged while running over an obstruction. Near its front end the runner-section is provided upon its upper side with a second lug or tenon 20, and the same has formed therein at its center a hole 21. The lug 20 is gradually tapered toward the front end of the runner-section and also has its opposite sides inclined. These inclinations of the sides agree with the inclination of the sides of the lug 15, and like the latter lug, the lug or tenon 20 is formed within the upper side-edges of the runner-section, so that shoulders 22 corresponding to the shoulders 5 of'the seed tube are formed.

In assembling the parts, as before stated, the lug 15 takes under the heel-portion of the seed tube, and the tenon 4 of the foot of the seed tube is of such shape and proportion as to fit snugly within the space formed between the rear end of the lug 20 and the front end or side of the lug 15 of the runner-section. When these parts are assembled they are slipped between the opposite steel-plates 11, and these plates are provided with holes 23, which it will be observed, align with the holes 7, 17, and 21, and through the same rivets are passed the aforesaid rivets serving to securely bind the parts together and make the shoe as rigid as if the same were formed integral. It will be seen that the forward edges of the plates 11 are curved, as at 24, and this curvature is continued by the curve 13 of the runner section so that the lower furrow-forming edge of the device is continuous, as is usual.

In Fig. 6 we have shown a slightly modified construction of runner-section shoe, and in this instance, the difference simply consists in providing at the rear edge of said section the depending ears or wings 25, the same forming the side walls of the seed-opening 26, which is formed in the runner-section and its upper extension or tenon 27. Such a construction forms a wider furrow than would the runner section 12, and hence is better adapted for the planting of corn.

It will be seen that when the parts are assembled the shoulders 22 of the runner-section and those shoulders 5 of the seed-tube are of a width agreeing with the thickness of the steel-plates 11, so that when said plates are interposed between said shoulders, the external sides of the entire device are smooth and unbroken and hence offer no obstruction to a ready passage of the device through the soil. Furthermore, by inclining the rear ends of the runner-sections loose soil cannot accumulate therein nor can seed, and hence serve to clog the opening, so that, as will be obvious, the opening will be clear, and the seed may be readily dropped therethrough into the furrow.

The essential feature of this invention resides in the tenon connection between the seed tube and the runner section; also in the disposition of the side plates whereby they serve to secure the parts together, besides covering the tenon connection.

It is to be understood that changes in the form, proportion and the minordetails of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described our invention, what we claim is- 1. In a shoe drill attachment, the combination with a seed tube having a seed passage, of an independent runner section having at its rear end an upwardly extending hollow lug or tenon adapted to interlock with the .lower end of the seed tube, the bore of the tenon aligning with the passage of the seed tube to form acontinuation thereof, substantially as specified.
